The shipping ship sailed several years ago for sellers in the US. The US Postal Service raised international rates into the stratosphere and killed off a the international market for a lot of businesses. Since the late 90s my side gig has been selling fine books (fine press, limited editions) and the rate increase stopped 90% of my international trade. You're running into the same thing when the shipping costs as much or more than the item. In some business sectors, multiple vendors can conbine items into a single shipment to a single country, but that cost savings is confined to a few sectors. Certainly not guitar parts. It ships by air, so the weight difference between knobs and a bridge translates into higher shipping. It's us, not you. Sorry.
